A horrible discovery was made inside an apartment near 7th Avenue and Highland Thursday.
Animal rescuers found a number of cats and dogs inside an apartment belonging to a suspected hoarder.
Neighbors reported the bad smells and sounds.
"These people I believe they truly love animals, the problem is they love them to death literally," said Bretta Nelson, Arizona Humane Society.
"The ammonia smell is clearly overwhelming, you can smell it from 15 feet away."
At least 16 cats -- one of which was dead -- and 5 dogs were removed from the residence.
The animals were taken to AHS' Second Chance Shelter.
